睡眠质量对农村老年人生命质量的影响:心理健康的中介效应与跌倒风险的调节作用

The impact of sleep quality on quality of life in rural older adults:the mediating effect of mental health and the moderating role of fall risk

为探讨农村地区老年人睡眠质量与生命质量之间的作用机制,文章采用欧洲五维三水平健康量表、匹兹堡睡眠质量量表、12项目一般健康问卷与Morse跌倒风险评估量表调查M县农村老年人,并用Bootstrap法进行中介效应与调节效应的检验。结果发现,心理健康在老年人睡眠质量和生活质量之间起到部分中介作用(效应值为-0.197,95%置信区间为-0.331~-0.072),中介效应占总效应的43.8%;中介效应受到跌倒风险的调节(R=-0.020,P<0.01),在跌倒风险较高的老年人中观察到更大的影响。因此,跌倒风险调节了老年人心理健康在其睡眠质量与生命质量之间的中介作用。降低跌倒风险,可能会提升睡眠质量差、心理健康状况不佳的老年人的生命质量。

This study adopts EQ⁃5D⁃3L,Pittsburgh sleep quality index,GHQ⁃12,and Morse fall scale(MFS)to investigate older adults in M County and to explore the interaction mechanism between sleep quality and quality of life of the older adults in rural areas.The mediating and moderating effects were tested by the Bootstrap method.The results found that mental health partially mediated between sleep quality and quality of life among older adults(effect size-0.197,95% confidence interval-0.331 to-0.072),with the mediating effect accounting for 43.8% of the total effect.The mediating effect was affected by the risk of falls(R=-0.020,P<0.01),with a more significant effect observed in older adults with a higher risk of falls.Therefore,fall risk in rural older adults moderates the mediating role of mental health on the association between sleep quality and quality of life.Reducing fall risks may improve the quality of life among older adults with poor sleep and mental health.
